Definitions
- the distribution manifold 116 may be constructed from bioresorbable materials that do not have to be removed from a patient's body following use of the system 100 .
- Suitable bioresorbable materials may include, without limitation, a polymeric blend of polylactic acid (PLA) and polyglycolic acid (PGA).
- the polymeric blend may also include without limitation polycarbonates, polyfumarates, and capralactones.
- the distribution manifold 116 may further serve as a scaffold for new cell-growth, or a scaffold material may be used in conjunction with the distribution manifold 116 to promote cell-growth.
- the lower sealing member 122 may, for example, be an impermeable or semi-permeable, elastomeric material.
- elastomeric means having the properties of an elastomer.
- Elastomeric generally refers to a polymeric material that has rubber-like properties. More specifically, most elastomers have ultimate elongations greater than 100% and a significant amount of resilience. The resilience of a material refers to the material's ability to recover from an elastic deformation.
- FIG. 3A a portion of the system of FIG. 2 is presented in plan view.
- the system 100 has not been activated or has been activated but no leak has been detected.
- No leak is detected as shown by the absence of any color contrast on the leak-detection member 106 .
- FIG. 3B a leak path 166 is shown by color contrasts 168 on the leak-detection member 106 . While generally not visible (other than the color contrasts 168 ), the leak path 166 is shown with broken lines beginning at an edge or periphery 170 and extending to the distribution manifold 116 from where the leak flows into the reduced-pressure interface 164 .
